The Safety Thimble II is designed and manufactured 100% in the USA! It is a precision made CNC machined 6061 aircraft grade Aluminum heavy duty thimble. The Winch Safety Thimble is designed to prevent the thimble from getting pulled into the fairlead where most accidents happen in winching, often due to winch “run-on” from electric winches. The Safety Thimble II, unlike hooks and standard eye thimbles, do not scratch your fairlead which otherwise can cause damage to synthetic winch ropes. It is also the lightest and most versatile recovery option to be used with synthetic winch line.
